How is calicivirus transmitted to cats? - briefly

Calicivirus in cats is primarily transmitted through direct contact with infected cats or contaminated surfaces. The virus can also be spread indirectly through shared food and water bowls, grooming tools, and human hands.

How is calicivirus transmitted to cats? - in detail

Calicivirus, particularly feline calicivirus (FCV), is highly contagious and can be easily transmitted between cats through various means. Understanding these transmission routes is crucial for preventing the spread of this virus.

One of the primary modes of transmission is direct contact with an infected cat. This can occur when a healthy cat comes into close proximity with an infected one, allowing for the exchange of bodily fluids such as saliva during grooming or sharing food and water bowls. The virus is also present in nasal secretions, which means that sneezing or coughing by an infected cat can aerosolize the virus and infect other cats in the vicinity.

Indirect transmission through fomites is another significant pathway for calicivirus spread. Fomites are objects or surfaces that can carry and transmit infectious agents. In the context of FCV, these can include bedding, litter boxes, toys, and even human hands. The virus can survive on these surfaces for several hours to days, allowing for transmission when a healthy cat comes into contact with them.

Additionally, vertical transmission from a pregnant queen to her kittens is possible. If a queen is infected during pregnancy, the virus can be passed to her unborn kittens, leading to congenital infections. This route of transmission underscores the importance of maintaining good hygiene and monitoring the health status of breeding cats.

Moreover, calicivirus can be shed by infected cats for prolonged periods, even after they have recovered from clinical signs. This intermittent shedding poses a continuous risk of transmission to other cats in the environment. It is important to note that while calicivirus primarily affects cats, it can also be transmitted to dogs, although the reverse is not true—dogs do not transmit calicivirus back to cats.

To mitigate the spread of calicivirus, it is essential to implement strict hygiene measures such as regular cleaning and disinfection of shared spaces and objects, proper isolation of infected cats, and avoiding contact with potentially infected environments. Vaccination can also play a significant role in preventing infection and reducing the severity of clinical signs if exposure occurs.

In summary, calicivirus transmission to cats is facilitated by direct contact with infected individuals, indirect contact through contaminated surfaces, vertical transmission from mother to offspring, and intermittent shedding by recovered cats. Understanding these transmission routes is vital for developing effective strategies to control and prevent the spread of this virus in feline populations.
